Anthropic principle and our finely-tuned Universe

Anthropic principle and our finely-tuned Universe Ethan Siegel at Starts With A Bang!

How the mis-application of the Anthropic Principle has led factions of scientists away from the search for a natural, physical explanation of our Universe, and why that’s bad for everyone.

One of the first things you notice — and it’s self-evident if you think about it — is that the Universe is full of stuff. This in itself is a wondrous thing, because it didn’t need to be that way.

I always figured You were a Martian!

“The evidence seems to be building that we are actually all Martians; that life started on Mars and came to Earth on a rock,” says Professor Benner. “It’s lucky that we ended up here nevertheless, as certainly Earth has been the better of the two planets for sustaining life. If our hypothetical Martian ancestors had remained on Mars, there might not have been a story to tell.”

“Finding 10,000 near-Earth objects is a significant milestone,” said Lindley Johnson, program executive for NASA’s Near-Earth Object Observations Program at NASA Headquarters, Washington. “But there are at least 10 times that many more to be found before we can be assured we will have found any and all that could impact and do significant harm to the citizens of Earth.” During Johnson’s decade-long tenure, 76 percent of the NEO discoveries have been made.

Near-Earth objects (NEOs) are asteroids and comets that can approach the Earth’s orbital distance to within about 28 million miles (45 million kilometers). They range in size from as small as a few feet to as large as 25 miles (41 kilometers) for the largest near-Earth asteroid, 1036 Ganymed.

Asteroid 2013 MZ5 is approximately 1,000 feet (300 meters) across. Its orbit is well understood and will not approach close enough to Earth to be considered potentially hazardous.

Lots of resources to be developed for the expansion of humanity in space and the reduction of our impact on Earth, in a half century or so, when we will really understand we need it.

I always knew you were a Hologram!

Professor Skenderis has developed a mathematic model which finds striking similarities between flat space-time and negatively curved space-time, with the latter however formulated in a negative number of dimensions, beyond our realm of physical perception.
He comments: “According to holography, at a fundamental level the universe has one less dimension than we perceive in everyday life and is governed by laws similar to electromagnetism. The idea is similar to that of ordinary holograms where a three-dimensional image is encoded in a two-dimensional surface, such as in the hologram on a credit card, but now it is the entire Universe that is encoded in such a fashion.
